When the U.S. presidential election could not be decided on January 6, the House of Representatives voted for the president, the Senate voted for the vice president, and the House of Representatives voted by state, which has been the case since the 1880s.
美国大選在1月6日沒法決定時，众议院投票选举总统，参议院投票选举副总统，众议院按州投票，自19世纪80年代以来就一直如此。
